NBA selects Kalshi and Polymarket for preferred exchange partnerships

The NBA has designated Kalshi and Polymarket as its preferred prediction market exchanges. The arrangement also includes official data supplied through Sportradar and an integrity agreement involving the CFTC.

The supplied coverage, published Nov 3, 2026 · 6:24 AM ET, identifies those three elements but provides no source links or underlying article. Further details about the partnership’s terms are not available in the material provided.

Data and integrity accompany exchange selection

For prediction-market readers, the announcement combines an exchange partnership with a data arrangement and an integrity component. The material does not specify how Sportradar’s official data will be used or describe the obligations under the CFTC integrity agreement.

The accompanying summary says there was no significant new prediction-platform headline in the preceding 30 minutes beyond coverage of this deal, making the partnership its lead item. That observation describes the summary’s coverage window, rather than establishing when the agreement was reached.

What it means for prediction markets

• Preferred status: Kalshi and Polymarket are the named exchanges. The supplied material does not establish whether that designation is exclusive.
• Official data: Sportradar is identified as the data provider, but implementation details are not supplied.
• Integrity framework: A CFTC integrity agreement is part of the announcement; its scope and requirements remain unspecified in the available material.
